    public static interface Item.PropertySetChangeNotifier
extends Serializable
    The interface for adding and removing PropertySetChangeEvent listeners. By implementing this interface a class explicitly announces that it will generate a PropertySetChangeEvent when its Property set is modified.

    Note : The general Java convention is not to explicitly declare that a class generates events, but to directly define the addListener and removeListener methods. That way the caller of these methods has no real way of finding out if the class really will send the events, or if it just defines the methods to be able to implement an interface.
